Gifts tighten personal relationships and provide a means of communication between loved ones. People say that a gift lets the recipient（接受者） know we are thinking of them, and that we want to make the person “feel special.”We want people to feel wanted, to feel part of our social or family group. We give presents to say “I’m sorry.”Sometimes it is difficult for us to find a present that someone will like. Sometimes we give things that we like or would frrl comfortable with. In all these cases, the gifts are sending out messages－often very expressive ones.
